Lily Allen has joined the Labour leadership battle by backing Ed Miliband after teasing his brother David over his choice of restaurant.

The singer's intervention came after David said his favourite restaurant was a North London curry house.

Asked by a newspaper to reveal the "best meal you've had in London", the former Foreign Secretary said: "I had a fantastic takeaway from Masala Zone in Camden recently." But Labour supporter Lily, who is pregnant, tweeted to her 2.3 million followers: "I've eaten there myself and while the food is perfectly nice, I very much doubt that it is the BEST meal you've had in London."

Mr Miliband tweeted in response: "I said Masala Zone because they do great takeaways but am going there next Monday if you fancy joining us."

Lily then completed her teasing of the older brother with: "Why did David Miliband cross the road? To get to the middle. Vote Ed."
